Quizplus · Accepted Answer

In a typical negative feedback loop involving hormone secretion, the hypothalamus (d) secretes releasing hormones that act on the anterior pituitary (e), which in turn secretes hormones that act on other endocrine glands or tissues. The posterior pituitary is not directly involved in this type of regulation through releasing hormones from the hypothalamus; it stores and releases hormones produced by the hypothalamus. The thalamus is not involved in hormone regulation.
